SGMICRO SGM452TS8G/TR

The SGM452 is an industry-standard digital temperature sensor integrating a sigma-delta ADC and I²C interface. The device offers ±1°C accuracy over the -20°C to +85°C range and ±1.2°C accuracy over the -55°C to +125°C range. The SGM452 provides 12-bit digital temperature readings. The device operates from a 2.7V to 5.5V supply voltage. Communication with the SGM452 is via the I²C interface, supporting operating frequencies up to 400kHz. Three address pins allow up to eight SGM452 devices on the same I²C bus. The SGM452 features a dedicated over-temperature output with programmable limits and hysteresis. The programmable fault tolerance of the output allows definition of the number of consecutive fault conditions that must occur before the OS is activated. The wide temperature range, wide supply range, and I²C interface make the SGM452 well suited for a broad range of applications where thermal management is critical to performance, such as wireless base stations, laptops, and personal computers. The SGM452 is available in RoHS-compliant SOIC-8 and MSOP-8 packages, with an operating ambient temperature range of -55°C to +125°C.
